Downloading extra content on Mobile

[glenwrhodes]

I'm looking at creating an app (In Unity) for the Wave SDK, that would include some larger 360 stereo video files in the 1GB range.  

 

I know that on the Google Play store you can package extra content as an addon downloadable, but does Viveport on mobile have anything similar?  

 

If not, what routes are developers typically taking to get extra content beyond the current 250 MB limit?

 

Any advice would be welcome!
